This is not really a solution, but read on... I had these symptoms in my 42 inch Hitachi plasma also.When I took it in to get it looked at , I was told that dust was accumulating on and around the cooling fans.He gave it a quick cleaning ( vacuuming I assume) and it worked for a while then started malfunctioning again. Now I'm trying to decide whether to just pitch it or keep cleaning it myself.Hope this helps.

Why does my panasonic tc p50st30 tv menu not work, tv will turn on but can not shut it off unless I unplug tv.


I would believe this to be a problem with the lvds cable that goes from your logic board to the main board. If your tv does not have a logic board, then it would have to be incorporated into the main board. A lot of times the connection gets loose on the main to logic board. If you reseat it, it may fix itself. If nothing else, you can pick up a logic board on ebay for around 25 dollars with shipping. It is usually very easy to replace. Most of the time, it's hidden behind the A board known as the Main board. It would probably take less than an hour to put in for someone not familar with the internals of a tv. Just MAKE SURE the tv is NOT plugged into the AC line.

SOON AS I TURN MY TV ON IT SHUTS RIGHT BACK OFF


It sounds like a repair is required, but to confirm:

With this model, you can try unplugging from the wall for at least thirty seconds, then plug in and switch on. (That's if you haven't already).

If that doesn't work, there is a fault causing the power supply to self protect and shut down again. Repair will be needed.

I have a 2006 Hitachi Ultravision 42 inch plasma


plasma tv units use a lot of power ,well into the hundreds of watts 9 some big screens use up to 800 watts to work)
I suggest that you consider a new led unit which uses barely any power and you will get a remote with it

My 42HDS69 Hitachi has a recurring problem of not turning on. I unplug from outlet for awhile and sometimes it will turn after I plug in outlet, Other times it takes a few hours for TV to turn back on. ...


MY TV KEPT GETTING WORSE EACH DAY ALSO. BUY A CAN OF SPRAY AIR WITH THE EXTENSION SPRAY TUBE. WHEN YOU GET THE TV RUNNING SPRAY THROUGH THE HOLES IN THE BACK RIGHT ONTO THE FAN BLADES OF BOTH FANS. THE DUST WILL FLY OFF THE BLADES. A VACUMM HOSE WILL HELP PULL OUT THE DUST. ALSO SRAY THE POWER SUPPLY BOARD FOR DUST. I APPEARS THE FANS SLOW DOWN WITH DIRT ON THEM AND THE EXTRA HEAT BUILD UP JUST AFTER THE TV IS SHUT DOWN IS CAUSING THE POWER SUPPLY TO BE IN A SHUT DOWN MODE WHEN POWERED UP THE NEXT TIME. BEEN TWO WEEKS NOW AND WORKS PERFECTLY NOW AGAIN.
